Definitions
- the present invention relates to a novel hydantoin-substituted acylacetanilide compound that is useful as an intermediate of the yellow coupler for use in a silver halide color photographic light-sensitive material, and to a method of manufacturing the compound.
- a yellow coupler for use in color photography generally used compounds are composed of a pivaroylacetanilide skeleton or a benzoylacetanilide skeleton, as a basic skeleton, and a 5-membered heterocyclic ring, such as hydantoin, located at a reaction point of the compound in a dye-forming reaction (see, for example, JP-B ("JP-B" means examined Japanese patent publication) Nos. 10739/1983, 45135/1981, and 44420/1981).

- This compound is generally synthesized by the method illustrated below. That is, a ⁇ -ketoester compound 1, as a key intermediate, is reacted with aniline, to obtain an acylacetanilide compound 2. The compound 2 is further subjected to halogenization, to obtain compound 3, followed by a substitution reaction, to obtain a yellow coupler of general formula (A).
- this method has several problems, as described below. For example, during the course of the substitution reaction of the compound 3 to obtain the yellow coupler of general formula (A), the compound 2 is sometimes obtained by reduction, because the compound 3 is an active halide substituted by two electron-attractive groups.
- the compound 3 provides a pKa value as low as that of hydantoin compound, and the compound 3 lowers reactivity of the hydantoin compound under a reaction conditions. Therefore, in order to complete the reaction, it is necessary to use a hydantoin compound represented by formula: in an excess amount of the compound 3. Accordingly, it has been desired to resolve such problems.
